I concur.  My feeling is that the best way is to use
an eddy current chassis dyno and hold the vehicle
steady-state under a given load, and then adjust the
timing using EGA, and possibly EGT as a backup.  This
is assuming you have already optimized the fuel map
for best power across the board.

My experience has been that when tweaking an engine
designed for performance (sportscar/motorcycle), you
should have to do little or no modification to the
fuel mapping after optimizing the timing.
